Nrrnn STATES einem PATENT SPECIFICATION forming part of Letters Patent No. 503,245, dated August 15, 1893.

Application filed July 12, 1892.

T0 all whom it may concern:

Be it known that I, FREDERIC H. MOORE, a

citizen of the United States, residing atk Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Bridging for Flooring-Joists, of which the following, taken in connection with the accompanying drawings, is a specification.

My invention relates to improvements in adjustable metallic bridging for lioor joists whereby the said bridging can be easily and readily applied even where there are slight differences of widths between the joists.

The invention consists of bridging pieces 0f metal preferably of wrought iron, each bridge consisting of three pieces, one long piece both ends-of which `are secured to the joist, and two short pieces, the outer end of each being secured to the joist, and their in ner ends interlocking with the Vlong piece which is preferably of a V shape as hereinafter fully described and pointed out in the claims. l Y

Referring to the accompanying drawings: Figure l is a perspective view showing two joists connected together by a metallic bridging embodying my invention. Fig. 2 represents the different/parts of the bridging disconnected. Fig. 3 is a perspective view showing two joists and a modified form of bridging. Fig. 4 is a view of the several parts o f the bridging disconnected. Fig. 5 is a View of joistsand bridging showing another method of connecting the bridging together. Fig. 6i is a view ofthe several parts of the bridging disconnected. Fig. 7 is still-another modification of connecting the several parts of the bridging.

A, A, represent the joists, B, a long piece of flat wrought iron bent into the Vform of a V, with its ends b, bent to t against the joist A, and near its apex are punched two rectangular holes d, d.

C, C, are two shortfpiecesY of fiat Wrought iron one end c, of each being bent to t against the joist A, and its otherV end being formed with a tenon e, that tits into the rectangular hole d, in the V shaped piece B, and when the parts are secured tothe joists, the inner ends of the pieces C, will be securely locked into Serial No. 439,847. l (No model.)

the piece B, thereby holding the parts rigidly in place. The tenon'may be'bentto lock with B as required.

In Figs. 3 and et I have shown the V shaped piece B, formed with round holes d', d', and instead of fiat bars C, I have shown round bars O', iiattened out at their outer ends c', to tit against the joist A, and their inner ends vloent to the required Vangle to pass through the holes d'.

In Figs. 5 and 6 I have shown a V shaped bar B2, and the two short bars C2, of flat metal Vsimilar to those described with vreference to Figs. 1 and 2, the only difference being the means of locking the parts together. In this case the bar Blis near its apex formed with two slots dand the ends e2, of the bars C2, are halved and bent round so as to lock into said slots, said ends being shown to return on an angle about equal to that of the piece B2, so that when in place they will be retained no matter in what direction the strain may be applied.

In Fig. 7 I have shown theV piece B2, of

the same construction as that shown in Figs.`

5 and 6,' and the piece C3, are also halved and tit into the slots, but they are constructed on a straight line, and not bent round as in Figs. 5 and 6.

Bridging thus constructed can be very easilyapplied as the V shaped piece B, is first secured to the joists A, and then the inner ends of parts C, inserted therein, and their' outer ends secured to the joists so that should there be any dierence of the width between the joists the bridging will readily accommodate itself thereto. I

Although I have shown and described a V shaped piece secured at both ends to the joists, it is obvious that any other suitably shaped piece might be employed, and instead of vsaid piece being pointed it might be curved round IOO
